Outline of Final Research Achievements

Metal cluster compounds have been expected to develop unique catalytic reactions by the use of synergism of the metal atoms held by direct metal-metal bonds. We have reported that molecular halide clusters with aqua ligands catalyze a wide variety of reactions. In these reactions, not the metal atoms but hydroxo (OH) ligands which were formed from the aqua ligands by thermal pre-activation mainly act as the catalytically active sites. In this research project, when solid-state metal halide- or sulfide-clusters without aqua ligands were used as catalysts, the metal atoms synergistically act as the catalytically active sites, catalyzing dehydrogenation of alcohols, decomposition of methyl tert-butyl ether (MTBE), dehydrogenative C-methylation of piperidine, and methylation of phenol selectively yielding o-cresol. This catalytic behavior is different from that of the molecular halide clusters with aqua ligands.
